A Lincoln Mark V, used the Ford C-6 from 1966-1979, nothing else is listed for it period. If it's a ford transmission, it will have a modulator on it. If your MekaniK is using the paint on it to identify the transmission and engine, I'd find another mechanic. I'm not a Ford Guy, but typically a Ford engine has the distributor on the front of the engine. Your 318 will have the distributor on the rear of the engine.
